* lockstatus() and VOP_ISLOCKED() gets a new process argument and a new
return value: LK_EXCLOTHER, when the lock is held exclusively by another
process.
* The ASSERT_VOP_(UN)LOCKED family is extended to use what this gives them
* Extend the vnode_if.src format to allow more exact specification than
locked/unlocked.

is good for... :-)), I discovered that part of the change when mkstemps()
was brought in was missed - it was missing the termination case to make
sure it doesn't walk into the suffix. This isn't the same code OpenBSD
has, I think this is a little better as we terminate the loop in a better
spot.

There's a possibility that there are still things wrong with the
commit. I wasn't able to build the version I committed, and I won't
be for another few days. If any committer finds further omissions,
the original source archive is on freefall:~grog/picobsd.tar.gz. Feel
free to correct.

The UPAGES have not been there since Jan '96, but the hole was preserved
for BSD/OS binary compatability. This has been fixed other ways (%ebx
now has a pointer to PS_STRINGS), and the stack is nowhere near where
it used to be so this hack isn't required anymore.
maps onto the upages. We used to use this extensively, particularly
for ps and gdb. Both of these have been "fixed". ps gets the p_stats
via eproc along with all the other stats, and gdb uses the regs, fpregs
etc files.
Once apon a time the UPAGES were mapped here, but that changed back
in January '96. This essentially kills my revisions 1.16 and 1.17.
The 2-page "hole" above the stack can be reclaimed now.

and fixing some major bugs.
- Add support for the v5 firmware interface, used by the DAC1164P
(tested) and AcceleRAID 352 (untested but should work). We now cover
all of the Mylex family's protocols except for v2 (used by EISA and
Alpha-compatible cards).
- Fix an accounting bug which resulted in endless 'poll still busy'
messages. In situations of high controller load the count of poll
commands could be incremented without actually successfully launching
a command. This totally removes the accounting for status poll
commnads; it was its own worst enemy.
- Add some simple reentry prevention locks to processing of the waiting
and completed command queues to prevent races which could result in
I/O being done or completed twice (both are fatal). This highlights
a need for simple locking primitives in both the UP and SMP kernels.
- Streamline the handling of command completion to reduce the amount of
redundant work being done. Remove the code which tests for commands
that have gone missing in action; nobody has ever seen one of these
and it wouldn't have worked properly anyhow.
- Handle disconnection of drives from the controller in the detach,
not shutdown method. This avoids problems flushing the cache in
a panic when a drive is mounted.
- Don't call bus_generic_detach when disconnecting drives; it doesn't
actually do anything useful.
- Increment the log message index regardless of whether we actually
retrieved one or not. If we run into a message that we can't fetch,
we don't want to spin endlessly complaining about the fact.
- Don't assume that interrupts will work when we're flushing the
controller. We may think they are enabled, but in eg. a panic
situation the controller may not be able to deliver an interrupt.

all the programs on the fixit floppy, which could thus also die.

anything useful on the remainder of the floppy. The current method
creates a larger mfs and can read as many floppies as the user can

attaching to the device via chip*, use the newbus nomatch method to report

loaded to grab them later.
o be more careful about clearing addresses (this isn't a kludge)
o For AF_INET interfaces, call SIOCDIFFADDR to remove last(?) bit
of cruft.
Special cases for AF_INET shouldn't be here, but I didn't see a good
generic way of doing this. If I missed something, please let me know.

o Build tools before doing anything in or with the object tree.
o Tools don't use the object tree any more, but have there object
tree located in the temp. world.
o Use the proper make env. for cleaning and building the object tree.
o Don't create kernel include subdirectories in the temp. world. These
are removed later on and replaced by symlinks.
o Change the layout of the object tree:
The temp. world now is /usr/obj/${MACHINE_ARCH}${.CURDIR}/${BUILD_ARCH}.
/usr/obj can be set/changed by using MAKEOBJDIRPREFIX, and {.CURDIR}
obviously depends on where the source tree is located. MACHINE_ARCH
is the arch. for which the world is to be build and BUILD_ARCH is the
arch. on which we are building.
The object tree now is /usr/obj/${MACHINE_ARCH}${.CURDIR}.
This allows concurrent cross-builds and allows the object tree to be
shared on different archs., each doing the same cross-build. This of
course assumes that the output on Alpha (for example) is the same as
the output of an Alpha cross-build on i386 (for example).
The use of NOCLEAN is is still dangerous, but should be usable in many
more situations than before. It should now be possible to safely
restart an interrupted build with NOCLEAN without side-effects. Because
the tools don't share the object tree with the normal (cross-build), no
tools have to be rebuild.
These drivers were cloned from the ed and ep drivers back in 1994
when PCMCIA cards were a very new thing and we had no other support
for such devices. They treated the PCIC (the chip which controls the
PCCARD slot) as part of their device and generally hacked their way
to success. They have significantly bit-rotted relative to their
ancestor drivers (ed & ep) and they were a dead-end on the evolution
path to proper PCCARD support in FreeBSD.
They have been terminally broken since August 18 where mdodd forgot
them and nobody seems to have missed them enough to fix them since.
I found no outstanding PRs against these drivers.
